[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: This example provides a workpiece transfer anti-deviation positioning device with guide groove, such as... Figure 1-5 As shown, the workpiece transfer anti-deviation positioning device includes a base 1, a fixed frame 2 and two sets of adjustment structures 3 symmetrically arranged on the end face of the base 1. The fixed frame 2 is slidably mounted with a T-shaped slider 4 through a guide groove 21. A first cylinder 5 is installed at the bottom of the T-shaped slider 4. A gripper structure 6 is provided at the drive end of the first cylinder 5.
[0023] The gripper structure 6 includes a mounting plate 61 installed on the drive end of the first cylinder 5. A connecting cylinder 62 and a servo motor 63 are installed at the bottom of the mounting plate 61. A base 64 is provided at the lower end of the connecting cylinder 62. A limit rod 65 is installed on the base 64 through a sliding groove 641. A clamping plate 66 is slidably installed on the outer wall of the limit rod 65. A connecting rod 67 is rotatably installed on the upper end of the clamping plate 66. A screw 68 is provided at the drive end of the servo motor 63. A threaded block 69 is installed on the screw 68 through a thread.
[0024] In use, when the gripper structure 6 moves above the workpiece, the control center drives the drive rod of the first cylinder 5 to move downwards. The first cylinder 5 moves the gripper structure 6 downwards, causing multiple sets of clamping plates 66 to move downwards to the outside of the irregular workpiece. Then, the servo motor 63 is started to rotate forward, driving the screw 68 to rotate. The screw 68 drives the threaded block 69 to move upwards. The threaded block 69 moves upwards through multiple sets of second connecting pins 691, driving multiple sets of connecting rods 67. The connecting rods 67 slide the clamping plates 66 on the limit rod 65 towards the screw 68 through the first connecting pin 662, thereby driving multiple sets of clamping plates 66 to move synchronously towards the irregular workpiece. The multiple sets of clamping plates 66 are fixed to the outside of the irregular workpiece and a certain force is applied, thereby realizing the function of firmly clamping the irregular workpiece. This avoids the problem that the existing workpiece transfer anti-deviation positioning device has poor clamping firmness for irregular workpieces, which may cause the workpiece to fall during the transfer and transportation process, resulting in workpiece damage. This helps to improve workpiece processing efficiency.
[0025] In this embodiment, a second cylinder 7 is installed on the end face of the fixing frame 2, a push-pull plate 8 is installed on the end face of the second cylinder 7, a placement plate 9 is installed on the bottom of the base 1 and on the left and right sides, the bottom of the push-pull plate 8 is connected to the end face of the T-shaped slider 4, and an active groove 22 is opened on the fixing frame 2 and the push-pull plate 8 respectively.
[0026] In this configuration, with the second cylinder 7 and the push-pull plate 8, after the gripper structure 6 clamps the workpiece, the first cylinder 5 is driven to retract, pulling the gripper structure 6 and the workpiece upwards. Then, the drive rod of the second cylinder 7 is driven to extend, and the second cylinder 7 moves the push-pull plate 8 to the right. The push-pull plate 8 slides the T-shaped slider 4 to the right in the guide groove 21, so that the first cylinder 5 can follow the T-shaped slider 4. The gripper structure 6 follows the first cylinder 5 to carry the workpiece in a straight line for transport, so that the workpiece will not deviate during the transfer process and the workpiece is accurately transferred to the next processing stage.
[0027] In this embodiment, the chassis 64 is slidably connected to the clamping plate 66 via a sliding groove 641. A rubber pad 661 is provided on the clamping plate 66. A first connecting pin 662, which is rotatably connected to the connecting rod 67, is installed on the upper end of the clamping plate 66 via a connecting groove. A second connecting pin 691, which is rotatably connected to the connecting rod 67, is installed on the threaded block 69 via a connecting groove. Multiple sets of sliding grooves 641 are provided and distributed in a circular array on the chassis 64. A bearing at the center of the chassis 64 is rotatably connected to the lower end of the screw 68. A through groove is provided on the connecting cylinder 62 corresponding to the connecting rod 67.
[0028] In this design, the rubber pads 661 allow multiple sets of clamping plates 66 to make flexible contact with the outer side of the irregular workpiece, thus avoiding damage to the workpiece caused by the clamping plates 66 directly contacting the workpiece rigidly, thereby protecting the workpiece.
[0029] Example 2: Unlike Example 1, the existing workpiece transfer anti-offset positioning device does not have the function of centering the workpiece, which makes it difficult for the fixture to accurately grasp the workpiece with the position offset, thus affecting the workpiece grasping efficiency. Therefore, the adjustment structure 3 includes a support plate 31 installed on the end face of the base 1. An electric push rod 32 is installed on the side wall of the support plate 31. The driving end of the electric push rod 32 passes through the support plate 31 and is equipped with an adjustment plate 33. A special-shaped tube 34 is installed on the end face of the support plate 31. A photoelectric sensor 35 is provided at the other end of the special-shaped tube 34.
[0030] In use, the photoelectric sensors 35 on the front and rear sides sense the workpiece on the placement plate 9. When the photoelectric sensor 35 senses the workpiece, it transmits information to the controller. The controller inputs information to the control center, which then activates the electric push rods 32 on the front and rear sides. The two sets of electric push rods 32 move closer to each other, driving the workpiece to the center position on the placement plate 9 for accurate positioning. Then, the electric push rods 32, along with the adjustment plate 33, return to their original position. The control center then activates the first cylinder 5, which moves the gripper structure 6 to the outside of the workpiece. The gripper structure 6 accurately grasps the workpiece, avoiding the problem that existing workpiece transfer anti-deviation positioning devices do not have the function of centering the workpiece, making it difficult for the fixture to accurately grasp workpieces with misaligned positions. This improves the workpiece grasping efficiency.
[0031] In this embodiment, a connecting plate 36 is installed on the upper side of the adjusting plate 33, and a guide rod 37 is installed on the side wall of the connecting plate 36. The support plate 31 is slidably connected to the outer wall of the guide rod 37 through a connecting hole.
[0032] The connecting plate 36 and the guide rod 37 provide guidance for the adjustment plate 33 as it moves back and forth, preventing the adjustment plate 33 from shifting during the movement.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
